The League of Nations played an integral role after World War I in attempting to maintain peace and prevent future conflicts. Established by the Treaty of Versailles in 1919, the League aimed to provide a forum for resolving international disputes and promoting disarmament. It sought to foster cooperation among nations through collective security measures. Despite its intended purpose, the League faced challenges such as a lack of participation from major powers like the United States and difficulties in enforcing its resolutions. Ultimately, its inability to prevent aggression in the 1930s and the onset of World War II highlighted its limitations, leading to its eventual dissolution.
